Special counsel Robert Mueller has recalled for questioning at least one participant in a June 2016 meeting between then-candidate Trump’s aides and a Kremlin-connected lawyer at Trump Tower, the Los Angeles Times reports. The identity of the person called back for further questioning has not been released, but the investigation’s renewed focus on the meeting is widely viewed as a sign Mueller is seeking to charge Trump or his aides with obstruction of justice. The meeting between Trump’s closest aides and Russian lawyer Natalia Veselnitskaya has been a source of intrigue since The New York Times first reported it in July, revealing that Donald Trump Jr. had allegedly agreed to the sit-down after being promised damaging information on Hillary Clinton. Mueller’s team is reportedly looking into whether Trump or other members of his administration knowingly lied when the White House issued a statement saying participants of the meeting only discussed an adoption program. Investigators are also reportedly scrutinizing Ivanka Trump’s involvement. The president’s daughter did not attend the meeting but briefly interacted with Veselnitskaya and lobbyist Rinat Akhmetshin as they were leaving the building, according to the report.
